I have a 4.0 OHV with 162xxx miles on it. I was wondering how much more miles can i get out of it if i keep doing the standard matinience on it?? My uncle is a Ford Machanic and says its almost dead (but he hated fords so im not to concerned about what he says) but it jus got me wondering. I dont have to much money or time to rebuild or get a new engine so i kinda need to knw. Thanx!
